Wiring

Follow the wiring instructions furnished by the 
appliance manufacturer, if available, or use the 
general instructions provided below. When these 
instructions differ from the appliance manufacturer, 
follow the appliance manufacturer instructions.

IMPORTANT

All wiring must comply with applicable electri-
cal codes and ordinances. 

WARNING

Electrical Shock Hazard or Equipment 
Damage Hazard.
Can cause serious injury, death or equipment 
damage.

Disconnect power supply before making wiring 
connections to prevent electrical shock or 
equipment damage.

1.

Check the power supply rating on the gas control 
and make sure it matches the available supply. 
Install a transformer and other controls as 
required.

2.

Connect the control circuit to the gas control 
terminals. See Fig. 4 and 5.

3.

Two stage gas valve wiring:

MV

 - Main valve or low fire.

C

 - Common terminal of ignition coils.

HI

 - Second stage or high fire.

4.

For single stage controls (VR8215S,T):

 

adjust thermostat heat anticipator to 0.50A 
rating stamped on valve label.

For two stage controls (VR8215Q,N):

 

adjust thermostat heat anticipator to 0.90A 
rating stamped on valve label.
